Re: [Discuss-gnuradio] Get error 3 when trying to connect to RTL-SDR

Hi, I think you've forgotten to blacklist the dvbt driver. In Ubuntu, you have to add the following line to /etc/modprobe.d/blacklist.conf: blacklist dvb_usb_rtl28xxu. best Federico 2017-09-28 17:11 GMT-03:00 Ed Troy : > I am trying to run a simple fm receiver example using a RTL-SDR dongle. It >

Hi Ed, I haven't heard of that block so far. So, maybe, it's really just a creation of that one author. In any case, I wouldn't know what you'd need it for. Best regards, Marcus On 09/28/2017 10:18 AM, Ed Troy wrote: > I am trying to set up a gnuradio-companion system on a Ubuntu 17.04 > machi

[Discuss-gnuradio] Can't find "usrp simple source" in pybombs install of gnuradio-companion

I am trying to set up a gnuradio-companion system on a Ubuntu 17.04 machine that is within VMWare. I seem to be almost there, but when I import an example, it all looks good except there is one missing block. It is "usrp_simple_source". How can I add this to gnuradio-companion? I have installed

Re: [Discuss-gnuradio] Timer-Chronometer

Hi Ali, You're getting into hand-waving territory there – I'd recommend you'd not use your PC time as an indicator of when flow graph operation started. Instead, you should count how many items your source has already produced, and divide that number by the sampling rate. This is one of the /very
